What REALLY lies beneath: First 'nuclear' map of our planet sheds light on Earth's interior and reveals man-made radiation activity

What goes on beneath Earth's crust is one of the biggest mysteries facing geophysicists.

Scientists have a rough idea of how much heat is produced from Earth's interior – but exactly where that heat is produced has, until now, been difficult to pinpoint.

Now, a new map of global antineutrino emissions could shed light on our planet's interior, as well as the heat processes that take place within it.
